ABB Contactor Standard Selection Procedure
(Industrial & Building, for sales / اقتباس / design)
Using ESB (building) and AF/A (صناعي) as examples – 8-step precise selection ready for proposals and quotations.
- Define Application & Product Family
Building / Residential / Distribution board: إضاءة, التدفئة, مضخات, المشجعين, small motors → ESB/EN series (silent, DIN rail, narrow width)
Industrial / معدات / Control cabinet: المشجعين, مضخات, الضواغط, motor main circuits → AF/A series (الجهد واسعة, long life, heavy-duty)
- Determine Load Category (Critical for Derating)
Per IEC 60947 utilization categories:
ايه سي-1: الأحمال المقاومة (سخانات, إضاءة) → use rated current directly
ايه سي-3: Squirrel-cage motor DOL (most common industrial) → motor current ≤ contactor rated current
AC-7a/7b: Building small motors, المشجعين, pumps → use building contactor rated values
- Calculate Operating Current & القدرة المقدرة
- Determine current from power / الجهد االكهربى
- Allow 1.1–1.25x safety margin (inrush, continuous duty)
- Select corresponding rated current (أي) from ABB catalog
مثال: 230V single-phase 2kW heater ≈ 8.7A → ESB20-20N is sufficient
- Select Number of Poles
1ص: مرحلة واحدة, single circuit
2ص: مرحلة واحدة, double-pole (L+N switching, building standard)
3ص: Three-phase motors / صناعي (most common)
4ص: ثلاث مراحل + N or double-break
- Select Coil Voltage & يكتب
- Control voltage: 24V, 110V, 230V, 400V, إلخ.
- نوع الملف:
Building: AC/DC universal coil (ESB series, non-polar, silent)
Industrial: لفائف واسعة النطاق (AF series, stable at 85–110% Un)
- Define Auxiliary Contact Requirements
مدمج: From model (20=2NO, 02=2NC)
Expandable: EH series auxiliary contacts (1لا + 1NC, 2لا, إلخ.)
Used for: Status feedback, interlocking, sequential control
- Environmental & متطلبات خاصة
ارتفاع >1000م, درجة حرارة >40°C → derate or upsize
Silent requirement (residential/office): Must use ESB silent type
حماية: IP20 normally sufficient for panel mounting
Mechanical interlock / عكس: Use dedicated interlock accessories
- Final Verification: نموذج + الشهادات
- Confirm full model: family–current–contacts–coil
مثال: ESB20-20N-06
- Verify certifications: سي سي سي, اللجنة الانتخابية المستقلة, RoHS
- تأكيد التثبيت: 35مم DIN السكك الحديدية / screw mounting
Simplified Selection Mnemonic
- Choose family by application
- Choose duty by load type
- Calculate current with margin
- Confirm poles and coil voltage
- Add aux contacts for control
- Check environment and derate
- Verify model for final list
